Although teacher responsivity education is viewed as benefitting children's language and literacy development, the impacts of this type of intervention on children's skills warrant further investigation.

In today’s research environment, children’s diet, physical activity, and other lifestyle factors are commonly studied in the context of health, independent of their effect on cognition and learning. Moreover, there is little overlap between the two literatures, although it is reasonable to expect that the lifestyle factors explored in the health-focused research are intertwined with cognition and learning processes. This thematic review provides an overview of knowledge connecting the selected lifestyle factors of diet, physical activity, and sleep hygiene to children’s cognition and learning. Research from studies of diet and nutrition, physical activity and fitness, sleep, and broader influences of cultural and socioeconomic factors related to health and learning, were summarized to offer examples of research that integrate lifestyle factors and cognition with learning. The literature review demonstrates that the associations and causal relationships between these factors are vastly understudied. As a result, current knowledge on predictors of optimal cognition and learning is incomplete, and likely lacks understanding of many critical facts and relationships, their interactions, and the nature of their relationships, such as there being mediating or confounding factors that could provide important knowledge to increase the efficacy of learning-focused interventions. This review provides information focused on studies in children. Although basic research in cells or animal studies are available and indicate a number of possible physiological pathways, inclusion of those data would distract from the fact that there is a significant gap in knowledge on lifestyle factors and optimal learning in children. In a climate where childcare and school feeding policies are continuously discussed, this thematic review aims to provide an impulse for discussion and a call for more holistic approaches to support child development.

This study tested the hypotheses that (a) persistent language difficulties during childhood would predict lower school readiness and (b) language difficulties present just prior to school entry would predict lower school readiness beyond any effects of persistence. The study involved examining indicators of school readiness collected at kindergarten for children exhibiting various histories of language ability based on language measures collected at 15, 24, 36, and 54 months by the National Institute of Child Health and Human Development's Early Child Care Research Network. Children (N ϭ 1,064) were classified according to whether they exhibited expressive or receptive language difficulties at each time point measured. The relation between persistence and timing of these difficulties to each kindergarten outcome was studied through a common factor approach for categorical outcomes. Persistence of language difficulties was not generally related to kindergarten outcomes. However, a robust effect was found for timing of language difficulties: Children who exhibited language difficulties at 54 months exhibited significantly depressed performance on measures of school readiness. Findings are discussed in terms of current policy and research concerning kindergarten readiness for children exhibiting risk.
